Thoroughly frustrated, hit several walls, sunk a lot of money and can’t get it right…

Hi, thought I had the right profile for this: I’m a product designer, good amount of business experience and specifically some in sourcing from China, a bit of an inventor and have ideas for new products. Though I’d go through the selling cycle first by white-labeling or doing a couple simple products and “prove that this works” by making some money to later develop my own simple products… well, I’m sure you already guessed that I did lose a lot of money and never gone over the first bump. Hired 4 different people to manage account, help me scout for products, etc, 3/4 ended up being flakes or borderline scammers, one of them was OK but simply won’t do his job. Down like $35k at this time, given up in recovering it (and if you saw my other post, still bleeding money through a buggy bill that Amazon sends me for immovable stock that it cannot even dispose of. Gaaahhhh.
